Star of the episode is an ancient forefather of Maestro who, after a journey of more than a 1,000 years, awakes near Omega, only to be greeted by descendants of humans who had made the trip after him, with better, larger and faster spaceships.

This episode excels in beautiful backgrounds and designs, especially of the spaceships. Highlight, however, are the ancient Maestro’s fantasies about extraterrestrial life, just before he encounters the all too familiar inhabitants of Omega.

With ‘Le long voyage’ we firmly return to the main story of ‘Il était une fois… l’espace’. The strange incident from episode 1 is mentioned again, and in this episode we learn that earth still exists, ultimately leading to our heroes visiting their mother planet in episode 17. It also contains an unclear mystery about a hijacked ‘train’, indicating more troubles to come. Moreover, this episode shows Psi’s psychic powers in full, saving Pierrot who has become adrift in space.

Maestro’s ancestor is a great character and he would return to the screen in episodes 17 (‘Terre!‘) and 18 (‘L’Atlantide‘).
